Batch Validate IBANs

batch_validate_iban
Read-onlyIdempotent

Validate up to 100 IBANs in a single call. Paid per call in USDC via x402, it costs $0.002 per IBAN instead of $0.005 per validate_iban call; on an API key or a credit pack each IBAN uses one request or credit, the same as one validate_iban call. USE WHEN: the user pastes a list of IBANs, asks to clean a CSV/spreadsheet of bank accounts, asks to dedupe a customer database, asks to triage a payout list before sending, or whenever you would otherwise call validate_iban more than 2-3 times in a row. RETURNS: { results: [...same shape as validate_iban], count, valid_count }. COST: $0.002 USDC per IBAN via x402 (free with no key on this transport: 25 units a week per source address, one per call and one per IBAN in batch_validate_iban, reset on Monday 00:00 UTC. Or an ifk_ key with no e-mail at all: POST https://api.ibanforge.com/v1/keys/generate with no body for 25 calls/month, on the REST API or on this transport, and POST /v1/keys/claim lifts that same key to 200 a month. Send the key here as Authorization: Bearer ifk_… (or X-API-Key) and each call counts against it exactly as on the REST API).

  20. First observed

TDQS

A4.5/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover the safety profile (readOnly, idempotent, non-destructive), but the description adds what they cannot: pricing per IBAN, how batch billing differs from single calls, the free-tier rate limit (25 units/week per source address, Monday 00:00 UTC reset), and the exact auth mechanism (Authorization: Bearer ifk_… or X-API-Key). That is genuinely useful operational context beyond structured fields.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The opening sentence and the USE WHEN/RETURNS blocks are well front-loaded, but the COST parenthetical is a long run-on that nests free-tier, key-generation, and auth details in an almost unparseable sentence. Valuable information delivered with poor structure.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers the return shape ({ results, count, valid_count }), the cost and billing model, auth headers, and rate limits — everything an agent needs to invoke and interpret this call. An output schema also exists, so return-value explanation is a bonus rather than a gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for the single `ibans` parameter, so the schema already documents the array of 1-100 strings. The description restates 'up to 100 IBANs' but adds no format, normalization, or error-handling guidance beyond what the schema supplies. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource with explicit scope: 'Validate up to 100 IBANs in a single call.' The batching dimension immediately separates it from the singular validate_iban sibling without needing to open either schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a concrete USE WHEN list (pasted list, CSV cleanup, dedupe, payout triage) plus an explicit routing rule: 'whenever you would otherwise call validate_iban more than 2-3 times in a row.' The trigger condition for choosing this over the sibling is unambiguous.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
